Abstract

A mains electrical plug incorporates a zinc oxide non-linear resistor device (10) in the form of a circular zinc oxide disc having three electrode portions (2) provided on one face and contacting the earth, neutral and live pins (5) of the plug and a single electrode (3) on its other face, the device (10) thereby providing surge protection to the three electrical circuits provided within the plug.
